SYNOPSIS

ARGUMENTS

Specifies the output context.
Specifies the output method.
Specifies the variable length argument list to set or
get XOC values.

DESCRIPTION

The
XCreateOC
function creates an output context
within the specified output method.

The base font names argument is mandatory at creation time, and the
output context will not be created unless it is provided. All other output
context values can be set later.

XCreateOC
returns NULL if no output context could
be created. NULL can be returned for any of the following reasons:
A required argument was not set.
A read-only argument was set.
An argument name is not recognized.
The output method encountered an output method implementation-dependent
error.

The
XDestroyOC
function destroys the specified output
context.

The
XSetOCValues
function returns NULL if no error
occurred; otherwise, it returns the name of the first argument that could
not be set. An argument might not be set for any of the following reasons:
The argument is read-only.
The argument name is not recognized.
An implementation-dependent error occurs.

Each value to be set must be an appropriate datum, matching the data
type imposed by the semantics of the argument.

The
XGetOCValues
function returns NULL if no error
occurred; otherwise, it returns the name of the first argument that could
not be obtained. An argument might not be obtained for any of the following
reasons:
The argument name is not recognized.
An implementation-dependent error occurs.

Each argument value following a name must point to a location where
the value is to be stored.

The
XOMOfOC
function returns the output method associated
with the specified output context.
